The Makefile and Kconfig changes don't apply at all. No idea how you
screwed that up, but you did.

The FIRST_20BYTE is not used. So remove it.

This is not used either and wrong on so many levels. Remove it.

And from here on. Please use tabs and not spaces. Did you actually run
checkpatch.pl on this patch?
